Surf soho wifi wan mac address

My surf soho is connected to an “open” AP for wifi wan. That “open” AP is a wifi hotspot that requires me to login to that ISP website and input the mac addresses of the devices I want to be able to connect to it. I have gone into the soho web admin under status and it says the wifi wan mac address but it doesn’t seem to work when I input it with the ISP. Like I said the soho is connected to that wifi wan but when I try to connect anything to the soho I get that ISP login page…
My be someone has run into this and can help me out…
Thanks
